GE’s GL 314 By-Pass Switch (BPS) is designed to close very fast and protect series capacitor banks in case of a fault in the overhead lines. It is equipped with excelled live tank circuit breaker technology such as the third-generation self-blast interrupter chambers and spring-operated mechanisms (FK). These field–proven interrupter chambers operate on the optimized self-blast principle. The FK3 type mechanisms equip the entire range of circuit breakers with more than 180,000 references worldwide.

The GL 314 BPS is field-proven and time-tested, providing high mechanical endurance and very low restrike probability according to IEC 622271-100 class M2 & C2. GE’s live tank circuit breakers provide a high level of reliability, even under extreme conditions and climates, and allow for quick, easy installation and commissioning with long intervals between maintenance.

High Quality Components

The GL 314 BPS live tank circuit breaker provides high reliability based in part on high quality components, including:

Three pole operating design

One self-blast interrupting unit with guard rings at upper and lower positions

Supporting column is composed of two to four insulators (depending on the voltage to ground/earth)

Spring mechanism FK3 equipped with a position indicator visible from the outside

The by-pass switch meets the requirements of national and international standards. This has been confirmed by comprehensive type tests according to the latest versions of IEC standards.

Certified Quality

GE's quality (ISO 9001:2008), environmental (ISO 14001:2004) and occupational health and safety (OHSAS 18001:2007) management systems determine the development and production procedures for the high voltage switches.
